Decided i will post a separate thread on this issue.
Vehicle detail: 1990 Cherokee, 150k, aw4.
Issue: Jeep stutters when pressing lightly on the gas while driving. It happens in every gear. Its apparent when accelerating lightly the truck feels like its pushing back and i can hear after fire in the exhaust. It seems like its around 2000 rpm. If i keep the truck in 1-2 gear and lightly accelerate i can make it misfire very violently from about 2k to 4k rpm. If i press on the gas harder the misfire is hardly noticeable it almost skips it.
What I have done so far: New TPS, adjusted and spot on. Replaced plugs, wires, rotor, cap, stator, o2 sensor. Got a coil and icm from a junk yard, still stutters the same.
Other modifications: New pacesetter header (old header had a crack), new magnaflow cat, used borla catback. Obviously new intake/exhaust gasket. All the CCV system lines are brand new. I checked every ground cleaned it and sprayed with anti-corrosion spray. Replaced braided ground with nice think insulated one. Cleaned pretty much every connector and filled with dialectic(sp?) grease.
The distributor rotor does not have much play in it, probably a degree or too, so i don't think the gear is warn.
I tried to check the timing with the light but i could not see anything.
What is the proper way to check timing with a timing light on Renix jeeps? Or is there even a way to do it?
This has been a huge pain for me to figure out. I am on a verge of bringing it to a shop but i know they will either charge me 500 dollars for diagnosis or will not figure out whats going on.
What scan tool does the shop have to have to be able to diagnose Renix?
